SPECIFICATION forming part of 'Letters Patent No. 253,993, dated February 21, 1882.

Application filed November 2l, 1881. (No model.) Patented in France September 16, 1875, and June 1S, 1881, and in England August E23, 1881.

ways, (for which I have obtained patents in France, bearing date 16th September, 1875, and 18th June, 1881, and in Great Britain, No. 3,674, dated 23d August, 1881,) of which the following is a specification.

My invention has for its object to improve generally the construction of the rolling stock of railways; and it consists mainly in applying to carriages, locomotives, and tenders a system of double suspension. for the body, so

as to obtain easier motion and consequentlydecreased wear and tear 5 and, further, in employing such' al construction as will enable wheels of very large diameter to be employed while keeping the center of gravity as low as possible, thereby enabling greater speeds to be obtained with 'increased' stability against running' 011' the rails or upsetting. yThe construction of the rolling stock for these pur-y poses will be readily understood on reference to the accompanying drawings, in which- Figures 1 to 3 show the improvements applied to a carriage.

elevation and part longitudinal section. Fig.

2 shows asectional plan on lineX X, and Fig.`

. 3 -shows a cross-section.

The body of the carriage is constructed entirelyof sheet and angleT ori.: iron,as shown. It is formed with an upper and lower story or floor. The lower story is divided into three compartments, of which the middle one, A, may be employed as a buffet or restaurant, from which accessis gained to the upper floor by 'the staircase a, arranged inthe space between l 5o means of wire ropes or by springs, and which Fig. 1 shows a part side.

in its turn is supported upon the wheels by other springs. For suspending the body by means of a wire rope, the rope m is attached at its ends to strong brackets M on the frame T by means ot' adjustable eyebolts m. This rope rests on rollers c2, attached to brackets c on the middle of cross-heads R, the ends of which are connected to rods c, whose lower ends are xed to the bottom frame of the body; or, when springs are employed, the rods c are connected byloops at their upper ends to the ends of springs R, that are supported at their middle by brackets r from the frame T. This frame isin its turn supported on the axle-boxes S2 of thewheel-axles J by means of springsS, the ends of which are attached by links to brackets S on the frame, which also carries .the horn plates S3.

For preventing longitudinal motion of the body when this is supported upon wire ropes, the axesof the suspension-pulleys c2 are connected by rods E to brackets F on the frame.

The frame is constructed of box shape, and its ends are curved downward,V as shown, so that the partl thereof formingthe buffer-beam is at a lower level. By this construction the frame possesses considerable elasticity against concussion in the case ot' collision, andthe fracture thereof and consequently of the body will in most cases be prevented.

Access is gained to the upper floor by means of external staircases, K, at the top of-which a platform is constructed on the same level as the floor, and there is also provided a hinged extension to the platform, that can be let down so as to establish a communication with the platform of the next carriage.'

As will he seen, this. construction of carriages allows of wheels of very large diameter being employed, the body being recessed at the respective points to receive them, as shown at Figs. 2 and 3. I

Figs. 4 to 9 show my improved construction as applied to a locomotive engine. Fig. 4 shows a longitudinal section. Fig. 5 shows a sectional plan; Figs. 6 and 6, cross-sections; Fig. 7,:a front view,'partly in section. Figs. 8 and 9 show detached details.

The cylindrical body A2 of the engine, together with the whole of the driving mechan- IOO ism, is suspended by transverse bearers a and suspension-rods a to the ends of the springs B, carried at their middles by brackets b, fixed to the frame C', which in its turn is suspended by bearers e4 and suspension-bolts from the ends of the springs D, carried on the axle-boxes of the wheel-axles.

The cylinders A are mounted beyond the frame on a plate, E2, xed to the boilerby means of a bracket, F, as shown at Figs. 6 and 8. On each sideof this bracket are vertical rails or ribs e2 e2 e2, that are in contact with rollers f f, carried on the transverse beams G of the frame C', so that the boiler has a tirrn abutment against the frame, preventing any relative longitudinal movement between the two, while at the same time the former can oscillate freely up and down within the latter upon its springs F3. The wheels of the engine lare also of large diameter.

Figs. 10,11, and 12 show respectively a 1011- gitudinal section, a sectional plan, and a transverse section of a tender constructed according to the present invention.

The body O of the tender is supported on transverse bearers f2, the ends of which are suspended by rodsf3 from the ends of springs R, carried by thc framing F4, which in its turn is supported by the springs S uponthe axle-boxes s ofthe axles G, which are ot' large diameter.

The lower part, O', ofthe tender constitutes the Water-tank, and as this is divided transversely into three separate compartments by the hollow partitions O2, through which the axles G pass, a communication is established between them bythe castings A, having passa-ges through which the water can flow from one compartment to the other, and which are provided with coeks at a* for running oft' the water.

The transverse part F ofthe frame F4 next the engine is lowered so as to be on the saine level as the foot-plate of the latter.

In all three constructions ofthe rollin g stock above described the 'Vestinghouse pneumatic brake can be applied as indicated in dotted lines. 1

Having thus described the nature of my invention and in what manner the same is to be performed, I claii 1. The combination, with an exterior frame sustained above the axles of the vehicle through the medium of springs, of the vehiclebody arranged over the said surroundingframe and extending downward below the same, thereby inclosing it, and springs or their described equivalent suspending the exterior body from the upper portion of the interior surrounding frame, substantially in the manner and for the purpose described.

2. The combination of an interior surrounding frame, T, sustained above the axle through the medium ofinterposed springs, the exteriorbody arranged over the interior frame and extending downward to inclose the same, and springs or their described equivalents suspending the exterior body from the upper portion of theiuterior frame, said body bein g vertically recessed at its sides to receive the supporting or. driving` wheels, substantially in the manner and for the purpose described.

3. The combination ot' the interior frame having the downward curved ends I, and supported on the axles through the medium of springs, with the exterior body arranged over said frame and extended downward to inclose the same, and devices, substantially as described, suspending the body from supports on the interior frame, substantiallyin the manner and for the purpose described.

4. In a locomotive-engine having its body suspended bysprings within a frame that is carried by other springs upon the wheels, the rollers f, carried by the said frame and' bearing against rails or ribs e2 011 the body, substantially as and for the purposes set forth.

5, In a locomotive-engine having its body suspended by springs within a frame that is carried by other springs upon the wheels, the connection of the cylinders A with the body A2 by means of the plate E2 and frame F2, substantially as herein described.

In testimony whereof I have signedmy name to this specification, in the presence of two subscribing witnesses, this 2d day of November, A. D. 1881.

AUGUSTE ESTRADE.
